WOLLASTONITE FOR FRICTION MATERIALS
Wollastonite in Friction Applications
Wolkem’s milled, HAR and surface modified Wollastonite grades are highly inert, acicular in nature and have a high melting temperature. These grades are used as secondary reinforcement fillers in dry mix non-asbestos organic friction materials such as brake linings, brake pads, clutch facings, friction papers and heavy-duty blocks.
Thermal stability and insulation
Improved wear and processing advantages
Increased tensile strength
Increased flexural modulus
Improved thermal insulation
Reduces wear
Reduces cracking
Reduces noise
Reduces costs
Cost-effective alternative to hazardous asbestos
The acicular structure and high melting temperature of Wollastonite contribute to reinforcement and thermal performance in friction materials.
Recommended Grade
Kemolit KW-60, Kemolit KW-4, Fillex 1AF-1 (KW)
